Bicycle Ergometer Training in Duchenne Muscular Dystrophy

Not Applicable

Completed

• Conditions: Duchenne Muscular Dystrophy
• Interventions: Other: Bicycle Ergometer Training; Other: Home-based exercise group

• Registration Number: NCT05330195
• Lead Sponsor: Hacettepe University

Brief Summary

The progressive muscle weakness and contractures of the patients adversely affect their gait and balance. It is known that the disorder of the patients' balance and gait affects their functional capacity. The aim of this study is to examine the effects of bicycle ergometer training on gait and balance in children with Duchenne Muscular Dystrophy. Twenty-four children with DMD included in the study will be divided into two groups as home program and home program+bicycle ergometer training with block randomization method. Home program including stretching, respiratory, range of motion, posture and mild resistance exercise with body weight will be asked to apply 3-5 days a week for 12 weeks, aerobic training will be performed 3 days a week for 12 weeks at 60% of their maximum hearth rate with 40 minutes total duration consisting of 5 min warm up and 5 min cool down period. Gait and balance were evaluated with GAITrite and Bertec Balance Check Screener, successively. Assessments will be applied at pre-training and after 12 weeks of training.

Arm && Interventions

Group	Intervention	Description
Treatment Group	Bicycle Ergometer Training	Home exercise program Children will be given a home program including stretching, breathing, normal joint movement, body weight and mildly resistant exercises, and children will be asked to do these for 3 to 5 days a week. Also, aerobic training will be performed 3 days a week for 12 weeks at 60% of their maximum hearth rate with 40 minutes total duration consisting of 5 min warm up and 5 min cool down period to children in treatment group
Treatment Group	Home-based exercise group	Home exercise program Children will be given a home program including stretching, breathing, normal joint movement, body weight and mildly resistant exercises, and children will be asked to do these for 3 to 5 days a week. Also, aerobic training will be performed 3 days a week for 12 weeks at 60% of their maximum hearth rate with 40 minutes total duration consisting of 5 min warm up and 5 min cool down period to children in treatment group
Control Group	Home-based exercise group	Home Based Exercise Group Children will be given a home program including stretching, breathing, normal joint movement, body weight and mildly resistant exercises, and children will be asked to do this program for 3-5 days a week.

Primary Outcome Measures

Name	Time	Method
Step Length, Stride Length and base of support (Gait)	5 minutes	The gait of patients with DMD was assessed by GAITrite (CIR Systems Inc., Franklin, New Jersey, USA) electronic walkway system, objective assessment of spatio-temporal characteristics of gait, at a self-selected speed for 3 times. With this walkway system,step length (cm), stride length (cm) and base of support (cm) were evaluated.
Velocity (Gait)	5 minutes	The gait of patients with DMD was assessed by GAITrite (CIR Systems Inc., Franklin, New Jersey, USA) electronic walkway system, objective assessment of spatio-temporal characteristics of gait, at a self-selected speed for 3 times. With this walkway system, Velocity (cm/s) was evaluated.
Step Time and Cycle Time(Gait)	5 minutes	The gait of patients with DMD was assessed by GAITrite (CIR Systems Inc., Franklin, New Jersey, USA) electronic walkway system, objective assessment of spatio-temporal characteristics of gait, at a self-selected speed for 3 times. With this walkway system, ambulation time (s) was evaluated.
Cadence (Gait)	5 minutes	The gait of patients with DMD was assessed by GAITrite (CIR Systems Inc., Franklin, New Jersey, USA) electronic walkway system, objective assessment of spatio-temporal characteristics of gait, at a self-selected speed for 3 times. With this walkway system, cadence (steps/min) was recorded.
Balance (rigid surface)	10 minutes	The balance plate system used to assess balance and degree of postural sway was the Bertec Balance Check Screener™ (BP5050 Bertec Co., Columbus, OH, USA). The system consists of a 20 × 20-inch platform at ground level connected to a computer. Postural sway, which measures the displacement of the center of gravity, was assessed on rigid surface, in 2 conditions (eyes opened-closed) and 2 directions (anteroposterior and mediolateral).
Single support, double support, swing phase and stance phase (Gait)	5 minutes	The gait of patients with DMD was assessed by GAITrite (CIR Systems Inc., Franklin, New Jersey, USA) electronic walkway system, objective assessment of spatio-temporal characteristics of gait, at a self-selected speed for 3 times. With this walkway system, single support, double support, swing phase and stance phase were stated as %.
Balance (perturbated surface)	10 minutes	The balance plate system used to assess balance and degree of postural sway was the Bertec Balance Check Screener™ (BP5050 Bertec Co., Columbus, OH, USA). The system consists of a 20 × 20-inch platform at ground level connected to a computer. Postural sway, which measures the displacement of the center of gravity, was assessed on perturbated surface, in 2 conditions (eyes opened-closed) and 2 directions (anteroposterior and mediolateral).
